How to choose sunscreen for each skin type?

To choose the best and most suitable sunscreen, you need to pay attention to the following issues:

1. SPF and PA index

SPF (Sun Protection Factor) is the index to measure resistance to UVB rays. The higher the SPF, the longer the time in the sun, each SPF protects the skin for about 10 minutes. To know how long the sunscreen works, simply multiply the SPF multiplied by 10.
For example SPF 30 = 30 x 10 = 300 minutes

However, note that the higher the SPF, the better.
PA (Protection Grade of UVA) index helps measure UVA resistance. With 3 levels, PA +, PA ++, and PA +++ correspond to weak UVA protection (4 hours), medium (8 hours), and strong (12 hours).

So what we need to remember is to choose a sunscreen with both of the above indicators for the best protection for your skin.

2. Properties of sunscreen

There are 2 main types of sunscreen: physical sunscreen, chemical sunscreen.

Physical sunscreens work as a protective barrier that prevents, diffuses, and reflects UV rays, making them unable to penetrate the skin. It is composed of Zinc oxide and Titanium dioxide.

Therefore, it has the advantage of being very benign to the skin, less irritating, and sustainable in the sun because the cream is like a wall, a layer for the skin. However, because this makes the skin have a white layer, easy to cause shine, and a little squash, causing acne if not taken care of skincare.

Chemical sunscreens act as chemical filters, absorbing and absorbing UV rays to self-treat and decompose before they damage the skin. Because of this, it has the advantage of penetrating quickly into the skin, not creating a shiny, white feeling like a physical sunscreen.
However, the downside is that it is not sustainable in the sun, so after 2 hours you should reapply. Currently, the K’Shi family has a sunscreen product that combines the advantages of the two above creams, you can consult.
